Given:
MgBr + HSO4 -> HBr +MgSO4

I react Zn metal with the mix to get a new product. Will a gas be given off, what is it ? What is the new balance equation??


I dont know what happens to the Zn on the products side.


Please help?? I do not know where to add the Zn.



given 150g MgBr and 150gHSO4
500mL dH2O

I have found:

1.44molMgBr
1.55molHSO4

2.8Molar (MgBr) 3.1Molar (HSO4)

we need 139.9gHSO4 to react with 160.82gMgBr.

139.0gHSO4 is the limiting reactant

The amount of product is:

116.83gHBr
185.57gMgSO4

Code: Select all

Zn + H{+} = Zn{2+} + H2 
:D

Code: Select all

H{+}
is from

Code: Select all

H2SO4
or

Code: Select all

HBr
